Among all the forces that bring your car to a halt, the most important of these are the brake backing plates. These steel plates are the very reason your car's braking system is held together to function. Without the brake plates, none of the other parts would work, so it's important to make sure that the brake backing plates are the first ones that do. Read on and learn the eight steps in replacing damaged brake backing plates:
Difficulty level: Moderate
Tools that you'll need:
- Lug nut wrench
- Socket and ratchet
- Tubing wrench
- Allen wrench
Step 1: Support the vehicle using a jack stand. Make sure there is enough room to allow yourself to work under your car.
Step 2: Remove the wheel and take off the two caliper bolts from the back of the caliper. Support the caliper with a bit of wire then remove it afterwards.
Step 3: Detach the rotor and set it aside. Unfasten the bolts holding the axle in. After this, place a catch pan under the end of the axle (since oil will come out). Locate the plate at the end of the axle and pull it out.
Step 4: Remove the bearing cap and pull the static clip out of the end of the spindle. Loosen the Allen nut from the spindle nut. Use a 3-jaw puller to detach the hub and inspect its seals and replace if necessary.
Step 5: Attach the brake lever into the rubber boot. Make sure it connects easily. Install the big spring into the upper-back side of both brake shoes. Also install these parts in order: the adjustment screw and the bottom spring, the pins and clips, and the skinny top spring.
Step 6: Install the brake cable end back into the lever. Adjust the shoes to fit the rotor hat. Slide the rotor hat on until the rotor just fits.
Step 7: Remove the protective towel and tape. Slide the hub assembly (with bearings) back over the axle end. Thread on the spindle nut and tighten.
Step 8: Take your car out for a test drive and adjust parking brakes as needed.
Brake backing plate replacement will take about 30 minutes for an expert DIYer and about an hour for a beginner.
